AMID a likely divorce from Catherine Zeta-Jones, MICHAEL DOUGLAS faces new heartbreak as his druggie son Cameron has been moved to a higher security prison.

The troubled 34-year-old – whose mother is Douglas’ ex-wife Diandra – has been transferred from a minimum security facility in Pennsylvania to the medium security Federal Correctional Institu­tion (FCI) in Cumberland, Md.

The transfer was most likely due to “behavioral issues,” Chris Burke, a public affairs specialist with the Federal Bureau of Prisons, told The ENQUIRER.

Such issues can range from a “history of drug abuse, escape attempts, as well as disciplinary and criminal histories,” Burke added.

Now, an insider says Cameron’s woes helped fuel his father’s split from Hollywood beauty Catherine after nearly 13 years of marriage and two children, son Dylan, 13, and daughter Carys, 10.

“Cameron’s problems caused constant grief for Michael and Cathe­rine,” a source told The ENQUIRER.

“Catherine felt Cameron was a spoiled kid who never got the discipline that he needed. She tried to push Michael into using ‘tough love’ with him, but Michael refused.

“Besides that, Catherine never wanted Cameron around their children, and it led to shouting matches between her and Michael.”

In May 2010, former DJ Cameron, who had been sentenced to a five-year term on drug charges, was transferred to the Federal Prison Camp in Lewisburg, Pa., which has no fencing.

But four and a half more years were tacked on to his sentence in December 2011 for drug possession while in prison.

In March 2012, Cameron was moved to the FCI in Loretto, Pa., where a brutal beating from other inmates left him with a broken leg and finger in December 2012.

The following January, a urinaly­sis revealed drugs in his system, and Cameron was sent to solitary confinement. He’s now in the FCI in Cumberland,Md.

When Michael won an Emmy for his role as Liberace in HBO’s “Behind the Candelabra” on Sept. 22, he gave a shout-out to Cameron, saying: “I’m hoping I’ll be able to…see him soon.”

Backstage, he told reporters that he’s not allowed to see Cameron “for two years” due to “punishment” for Cameron “having a slip.” He added that he’s very, very disappointed with the system.

Following Douglas’ remarks, The ENQUIRER contacted Federal Bureau of Prison spokesman Burke and asked if Cameron’s dad was allowed to visit him. Burke said he couldn’t comment on Cameron’s “disciplinary history of conditions.”
